Police sources said four suicide attackers infiltrated Khanpur during Eid prayers.
Two attackers targeted an Eid prayer ground where one attacker blew himself up, injuring 10 people, two of whom were policemen. The other attacker fled, police sources said.
Two other attackers targeted an imambargah but were stopped by police at the entrance on account of appearing suspicious. As the attackers attempted to flee, one was gunned down by a cop, whereas the other was arrested.
Those injured in the blast have been admitted to hospitals in Shikarpur for treatment.
